Answer

### a) 54### b) 92### c) -77### d) -56### e) 62### f) 387### g) -8

Explanation

## Step 1: Simplify by pairing opposites in (a)### We have (-45) and (+45) which sum to 0. Then we have (+48) + (+6) = 54. So, .## Step 2: Simplify by pairing opposites in (b)### We have (+23) and (-23) which sum to 0. Then we have (+87) + (+5) = 92. So, .## Step 3: Simplify by pairing opposites in (c)### We have (+76) and (-76) which sum to 0. Then we have . So, .## Step 4: Simplify by pairing opposites in (d)### We have (+6) and (-6) which sum to 0. We also have (-43) and (+43) which sum to 0. Then we have . So, .## Step 5: Simplify by pairing opposites in (e)### We have (-42) and (+42) which sum to 0. Then we have . So, .## Step 6: Simplify by pairing opposites in (f)### We have (-925) and (+925) which sum to 0. Then we have . So, .## Step 7: Simplify by pairing opposites in (g)### We have (-7) and (+7) which sum to 0. Then we have . So, .
